Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Number of Positions: 5 (exact match required)
• Pitch: 0.200" (5.08mm) for primary substitutes; 0.197" (5.00mm) represents a minor pitch variation
• Header Orientation: 90° right-angle for direct substitutes; vertical orientation represents a functional alternative
• Type: Male pins, shrouded (4 side) configuration
• Mounting Type: Through hole solder mounting
• Voltage - UL: 300 V minimum
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

Group 1 - Direct Equivalents (90° Right-Angle, 5.08mm Pitch):

• TE Connectivity 1776038-5
• Würth Elektronik 691313510005
• On Shore Technology OSTOQ055451

Group 2 - Minor Pitch Variation (90° Right-Angle, 5.00mm Pitch):

• Würth Elektronik 691313710005

Group 3 - Orientation Alternative (Vertical, 5.08mm Pitch):

• Amphenol Anytek OQ0554500000G

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Group 1): TE Connectivity 1776038-5, Würth Elektronik 691313510005, and On Shore Technology OSTOQ055451 are direct functional equivalents. All maintain 5-position, 0.200" (5.08mm) pitch, 90° right-angle orientation, and UL94 V-0 flammability rating. All are ROHS3 compliant and active products. TE Connectivity 1776038-5 features a slightly shorter contact tail length (0.126" vs. 0.138"), which may require PCB layout verification. Würth Elektronik 691313510005 supports higher UL current rating (20 A vs. 15 A) and is available in tray packaging. On Shore Technology OSTOQ055451 supports extended operating temperature range (-40°C to 115°C).

Minor Pitch Variation (Group 2): Würth Elektronik 691313710005 operates at 0.197" (5.00mm) pitch, representing a 0.03mm deviation from the primary specification. This part supports 20 A UL current and extended operating temperature. Pitch variation requires PCB footprint compatibility assessment before selection.

Orientation Alternative (Group 3): Amphenol Anytek OQ0554500000G provides vertical orientation instead of 90° right-angle. This represents a functional alternative for applications where vertical mounting is required. Current rating is 12 A (lower than primary part), and insulation height is significantly greater (0.472" vs. 0.339"), requiring board space evaluation.

All substitute parts maintain active product status, ROHS3 compliance, and UL94 V-0 flammability rating, supporting regulatory and environmental requirements equivalent to the primary part.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 1776038-5 be used as a direct replacement for Phoenix Contact 1757271? A: Yes. Both parts share identical position count (5), pitch (0.200"/5.08mm), orientation (90° right-angle), mounting type (through hole), voltage rating (300 V UL), and flammability rating (UL94 V-0). The contact tail length differs by 0.012" (0.30mm), requiring PCB layout verification to confirm clearance and solder joint integrity.

Q: What is the difference between the Würth Elektronik 691313510005 and 691313710005? A: The primary difference is pitch specification. 691313510005 operates at 0.200" (5.08mm) pitch, while 691313710005 operates at 0.197" (5.00mm) pitch. Both support 20 A UL current and identical orientation. The pitch variation requires PCB footprint compatibility assessment; these parts are not interchangeable on the same board layout.

Q: When should Amphenol Anytek OQ0554500000G be selected instead of the Phoenix Contact 1757271? A: OQ0554500000G is selected when vertical mounting orientation is required instead of 90° right-angle. This part is not a direct replacement due to orientation difference and lower current rating (12 A vs. 15 A). Board space requirements differ significantly due to increased insulation height (0.472" vs. 0.339").

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance status, matching the primary Phoenix Contact 1757271 specification.

Q: What packaging options are available for these terminal block headers? A: Phoenix Contact 1757271 is supplied in bulk packaging. Würth Elektronik 691313510005 is available in tray packaging. TE Connectivity 1776038-5, Würth Elektronik 691313710005, Amphenol Anytek OQ0554500000G, and On Shore Technology OSTOQ055451 are supplied in bulk packaging.

Q: Do all substitute parts support the same voltage and current ratings? A: Voltage rating (300 V UL) is consistent across all parts. Current ratings vary: Phoenix Contact 1757271 and TE Connectivity 1776038-5 support 15 A; Würth Elektronik parts support 20 A; Amphenol Anytek OQ0554500000G supports 12 A. Application current requirements determine part selection.
