Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

Primary Matching Criteria:

Number of positions: 2
Pitch: 0.200" (5.08mm) or 0.197" (5.00mm)
Header orientation: 90°, Right Angle
Type: Header, Male Pins, Shrouded (4 Side)
Termination style: Solder
Mounting type: Through Hole
Material flammability rating: UL94 V-0

Electrical Compatibility Criteria:

UL voltage rating: minimum 300V
UL current rating: minimum 12A (preferred 15A or higher)
Contact mating finish: Tin

Secondary Considerations:

Product status: Active status preferred for long-term availability
RoHS/REACH compliance: ROHS3 Compliant or RoHS Compliant
Housing material: Polyamide (PA), Nylon, Liquid Crystal Polymer (LCP), or Polybutylene Terephthalate (PBT)

Substitute parts are grouped into two categories: Direct 5.08mm pitch equivalents and Near-equivalent 5.00mm pitch alternatives. Parts with pitch deviation of ±0.08mm remain mechanically compatible within standard PCB tolerance specifications.

Engineering Selection Recommendations

Tier 1 — Direct Replacement (Highest Compatibility):

Phoenix Contact 1757242 is the primary substitute. It maintains identical electrical specifications (15A/300V UL), same pitch (5.08mm), same series family (COMBICON MSTBA), and active product status. ROHS3 compliance exceeds the original RoHS Compliant rating. This part is recommended for direct substitution in new designs and production restarts.

Tier 2 — Functional Equivalents (Same Electrical Performance):

HARTING 14120217002000 and TE Connectivity 1776038-2 both deliver 15A/300V UL performance with 5.08mm pitch and active status. HARTING offers enhanced voltage rating (600V UL) and multi-material housing options. TE Connectivity maintains Buchanan series compatibility. Both are suitable where Phoenix Contact supply is constrained.

Würth Elektronik 691313510002 provides superior current rating (20A UL) at 5.08mm pitch with active status and ROHS3 compliance, offering performance headroom for demanding applications.

Tier 3 — Near-Equivalent Alternatives (5.00mm Pitch):

TE Connectivity 1776148-2 and Würth Elektronik 691313710002 feature 5.00mm pitch (±0.08mm deviation from 5.08mm). Both maintain 15A/20A UL current ratings and 300V voltage rating with active status. These are suitable for new PCB designs where pitch tolerance can be accommodated.

Tier 4 — Conditional Substitutes:

Amphenol Anytek OQ0254510000G and On Shore Technology OSTOQ025451 meet core mechanical and electrical criteria with active status and ROHS3 compliance. OQ0254510000G specifies 12A UL current (matching IEC rating of original). OSTOQ parts lack specified UL current ratings; verification against application requirements is necessary before selection.

Phoenix Contact 1954919 (COMBICON CCA series) is electrically rated at 10A UL, below the original 15A specification. Selection requires confirmation that application current demand does not exceed 10A.

Frequently Asked Questions (FAQ)

Q: Can I use a 5.00mm pitch part as a direct replacement for the 5.08mm pitch original?

A: Yes, within standard PCB tolerance. The 0.08mm pitch deviation (±1.6%) falls within typical manufacturing tolerances for through-hole PCB pad spacing. TE Connectivity 1776148-2 and Würth Elektronik 691313710002 are mechanically compatible for new PCB designs. Existing PCBs designed for 5.08mm pitch require verification before substitution.

Q: What is the difference between IEC and UL electrical ratings?

A: IEC ratings (12A/400V for the original part) apply to international standards; UL ratings (15A/300V) apply to North American standards. Substitutes must meet or exceed the UL rating applicable to your market. All listed substitutes meet or exceed 300V UL voltage; current ratings vary from 10A to 20A UL.

Q: Is the housing material change from Polyamide to Liquid Crystal Polymer or PBT significant?

A: Housing material affects thermal performance, chemical resistance, and mechanical durability. Polyamide (PA), Liquid Crystal Polymer (LCP), and Polybutylene Terephthalate (PBT) all meet UL94 V-0 flammability requirements. Material selection depends on operating temperature range and environmental exposure. Verify compatibility with your application's thermal and chemical environment.

Q: Why is Phoenix Contact 1902741 obsolete?

A: Obsolescence reflects end-of-life status from the manufacturer. Phoenix Contact 1757242 is the active successor within the same COMBICON MSTBA series, offering identical performance with updated compliance certifications (ROHS3).

Q: Do all substitute parts have the same contact tail length?

A: No. Contact tail length varies: original 1902741 is 0.114" (2.90mm); substitutes range from 0.102" (2.60mm) to 0.157" (4.00mm). Longer tail lengths provide greater solder joint strength; shorter lengths reduce PCB footprint. Verify tail length compatibility with your PCB design before selection.

Q: Which substitute offers the best long-term availability?

A: Phoenix Contact 1757242 and Würth Elektronik 691313510002 both show high inventory levels (1310 and 2069 units respectively) with active product status. On Shore Technology OSTOQ025451 shows the highest inventory (24,274 units). For critical applications, confirm supplier lead times and forecast availability with your component distributor.

Q: Are all substitutes RoHS compliant?

A: Yes. The original 1902741 is RoHS Compliant; all listed substitutes are either RoHS Compliant or ROHS3 Compliant (enhanced standard). ROHS3 compliance is preferred for new designs and long-term supply chain stability.
