Phoenix Contact 1755635 Terminal Block Plug — Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1755635 is a 7-position terminal block plug designed for unshrouded headers with 0.197" (5.00mm) pitch spacing and 90° wire entry orientation. This COMBICON PT series component features screw-rising cage clamp termination, free-hanging in-line mounting, and supports wire gauges from 14–28 AWG (0.2–2.5mm²). The part is active in production with 1,141 units in current inventory.

Equivalent and substitute parts are identified when design requirements permit tolerance of minor pitch variations (5.00mm to 5.08mm), wire entry angle changes (90° to 180°), or termination method modifications (rising cage clamp to clamping yoke), while maintaining electrical performance within IEC and UL specifications.

Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 1755635 are grouped based on the following substitution criteria:

Primary Compatibility Parameters:

• 7-position terminal block plug configuration
• Pitch tolerance: 5.00mm (original) to 5.08mm (±1.6% variance acceptable in mechanical design)
• Wire entry angle: 90° (original) to 180° (design-dependent accommodation required)
• Termination method: Screw-based (rising cage clamp or clamping yoke variants)
• Free-hanging in-line mounting type
• Wire gauge support: 12–28 AWG minimum overlap
• Electrical ratings: UL 300V / 10A minimum compliance

Identified Substitute Groups:

Group 1: Molex Eurostyle ESE 39530 Series (0395300007, 0395305007)

• Pitch: 5.08mm (0.8mm variance from original)
• Wire entry: 180° (straight entry vs. 90° angled)
• Termination: Screw - Rising Cage Clamp (identical method)
• Current/Voltage: 15A UL / 300V UL (exceeds original ratings)
• Wire gauge: 12–26 AWG (overlaps original 14–28 AWG range)

Group 2: Weidmüller Unimate BLA Series (1282260000, 1356560000)

• Pitch: 5.08mm (0.8mm variance from original)
• Wire entry: 180° (straight entry vs. 90° angled)
• Termination: Screw - Clamping Yoke (alternative screw method)
• Current/Voltage: 17.5A IEC / 400V IEC; 10A UL / 300V UL (meets or exceeds original)
• Wire gauge: 12–26 AWG (overlaps original 14–28 AWG range)
• Housing material: Polybutylene Terephthalate (PBT), Glass Filled (vs. Polyamide)

Parameter Comparison

Engineering Selection Recommendations

Molex 0395300007 and 0395305007 (Eurostyle ESE 39530): Both parts maintain identical termination methodology (rising cage clamp) and housing material (polyamide nylon) to the original Phoenix Contact 1755635. The 5.08mm pitch represents a 1.6% mechanical variance. Wire entry angle changes from 90° to 180°, requiring design accommodation for cable routing. Current rating increases to 15A UL, exceeding original specifications. Both parts are ROHS3 compliant and active in production. Selection between these two variants depends on color requirement: 0395300007 is black; 0395305007 is green. Note that 0395305007 carries REACH Affected status, whereas 0395300007 is REACH Unaffected.

Weidmüller 1282260000 and 1356560000 (Unimate BLA): Both parts employ alternative termination technology (clamping yoke vs. rising cage clamp) and housing material (glass-filled PBT vs. polyamide nylon). Pitch remains 5.08mm. Wire entry angle is 180°. Both maintain UL 300V / 10A compliance and UL94 V-0 flammability rating. IEC ratings exceed original specifications (17.5A / 400V). Both are RoHS compliant and active in production. Housing material change (PBT glass-filled) provides enhanced thermal and mechanical properties compared to standard polyamide. Selection between these variants depends on retention latch requirements and color preference (both orange). Screw size differs (M2.5 vs. M3 in Molex variants).

Compliance Summary: All substitute parts maintain active product status, RoHS compliance, and UL 300V electrical rating. Flammability ratings are confirmed for Weidmüller variants (UL94 V-0) and original Phoenix Contact part; Molex variants do not specify flammability rating in provided data.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1755635 be directly replaced with a Molex or Weidmüller substitute without design changes?

A: Direct mechanical replacement is not possible without design accommodation. The primary difference is wire entry angle: the original part features 90° entry (angled), while all substitutes feature 180° entry (straight). This requires cable routing modification in the assembly design. Pitch variance (5.00mm to 5.08mm) is within typical mechanical tolerance but must be verified against header spacing in your application.

Q: What is the impact of changing from rising cage clamp to clamping yoke termination?

A: Both termination methods are screw-based and provide equivalent electrical connection security. Rising cage clamp (Phoenix Contact, Molex) and clamping yoke (Weidmüller) differ in mechanical clamping mechanism but deliver identical functional performance. Wire insertion and removal procedures may differ slightly; consult manufacturer documentation for specific handling requirements.

Q: Are there wire gauge compatibility concerns when substituting?

A: The original part supports 14–28 AWG. Molex and Weidmüller substitutes support 12–26 AWG. The overlap range is 14–26 AWG, which covers most applications. If your design uses 27–28 AWG wire, the Phoenix Contact 1755635 is the only option among these parts.

Q: Does housing material change affect electrical performance?

A: No. Polyamide (PA) nylon and polybutylene terephthalate (PBT) glass-filled are both suitable for terminal block housing. PBT glass-filled (Weidmüller) offers superior thermal stability and mechanical rigidity. Material selection depends on operating temperature range and mechanical stress requirements in your application.

Q: What is the significance of REACH Affected vs. REACH Unaffected status?

A: REACH Affected status (Molex 0395305007) indicates the part may contain substances of very high concern (SVHC) requiring compliance documentation. REACH Unaffected status indicates no SVHC content. For applications subject to REACH regulations, select REACH Unaffected parts (Phoenix Contact 1755635, Molex 0395300007, Weidmüller variants).

Q: Can I use a substitute part with higher current rating (15A Molex, 17.5A Weidmüller IEC) in a 10A application?

A: Yes. Higher current ratings provide design margin and do not create compatibility issues in lower-current applications. The substitute part will operate safely within your 10A design specification.

Q: What inventory considerations should guide my selection?

A: Current stock levels are: Phoenix Contact 1755635 (1,141 pcs), Molex 0395300007 (2,721 pcs), Molex 0395305007 (1,641 pcs), Weidmüller 1282260000 (879 pcs), Weidmüller 1356560000 (1,181 pcs). Molex 0395300007 offers the highest availability. All parts are active in production, supporting long-term supply continuity.
