Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0395310012 is determined by the following critical parameters:

Primary Compatibility Criteria:

• 12-position configuration
• Vertical through-hole mounting orientation
• Solder termination style
• Male pin header type with shrouding
• Pitch tolerance: 5.00mm to 5.08mm (0.197" to 0.200")
• Minimum voltage rating: 300V UL
• Minimum current rating: 12A (IEC) or 15A (UL)
• Operating temperature range overlap: minimum -30°C to 105°C
• UL94 V-0 flammability compliance
• ROHS3 compliance

Identified Substitute Parts:

1. Phoenix Contact 1753631 – Pitch 5.00mm, 12A IEC / 12A UL, 400V IEC / 300V UL, 2-side shrouding, meets all primary criteria with minor pitch variance within tolerance.

2. Amphenol PCD ELFH12250 – Pitch 5.08mm (exact match), 15A UL, 300V UL, 4-side shrouding (enhanced mechanical protection), identical electrical ratings, meets all criteria with upgraded shroud design.

3. On Shore Technology OSTOQ127150 – Pitch 5.00mm, 300V UL, 4-side shrouding, solder mounting, meets electrical and mechanical requirements with minor pitch variance and enhanced shroud configuration.

Parameter Comparison

Engineering Selection Recommendations

Amphenol PCD ELFH12250 is the primary substitute for direct replacement. It maintains identical pitch (5.08mm), current rating (15A UL), voltage rating (300V UL), operating temperature range (-40°C to 105°C), and flammability compliance (UL94 V-0). The 4-side shrouding provides enhanced mechanical protection compared to the 2-side design of the original part. Both parts are ROHS3 compliant and active in production.

Phoenix Contact 1753631 is suitable where minor pitch variance (5.00mm vs. 5.08mm) is acceptable within PCB layout tolerances. It maintains 300V UL voltage rating and UL94 V-0 compliance. Current rating is 12A UL, which is lower than the original 15A specification. This part is ROHS3 compliant and active in production.

On Shore Technology OSTOQ127150 accommodates applications where 4-side shrouding is preferred and pitch variance is acceptable. It maintains 300V UL voltage rating and ROHS3 compliance. Operating temperature range extends to -30°C minimum (versus -40°C for the original). Current rating is not specified in available documentation. This part is active in production.

All three substitutes are ROHS3 compliant, active in production status, and maintain the critical 300V UL voltage specification required for the application.

Frequently Asked Questions (FAQ)

Q: Can I use Phoenix Contact 1753631 as a direct replacement for Molex 0395310012?

A: Phoenix Contact 1753631 is functionally compatible with pitch tolerance considerations. The 5.00mm pitch differs from the original 5.08mm by 0.08mm, which may require PCB layout verification. The 12A UL current rating is lower than the original 15A specification. Both parts maintain 300V UL voltage rating, UL94 V-0 compliance, and ROHS3 status. Verify PCB footprint compatibility before implementation.

Q: What is the difference between 2-side and 4-side shrouding?

A: 2-side shrouding (Molex 0395310012) provides lateral protection on two opposing sides. 4-side shrouding (Amphenol PCD ELFH12250, On Shore Technology OSTOQ127150) provides protection on all four sides, offering enhanced mechanical stability and EMI shielding. Both configurations maintain the same electrical performance and voltage/current ratings specified.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Molex 0395310012, Phoenix Contact 1753631, Amphenol PCD ELFH12250, and On Shore Technology OSTOQ127150 are all ROHS3 compliant. All parts are active in production status.

Q: What is the pitch tolerance between substitute parts?

A: Molex 0395310012 and Amphenol PCD ELFH12250 share identical 5.08mm pitch. Phoenix Contact 1753631 and On Shore Technology OSTOQ127150 use 5.00mm pitch, representing a 0.08mm variance. PCB layout verification is required when mixing pitch specifications within a design.

Q: Which substitute maintains the exact electrical specifications of the original part?

A: Amphenol PCD ELFH12250 maintains identical pitch (5.08mm), current rating (15A UL), voltage rating (300V UL), and operating temperature range (-40°C to 105°C). It is the closest functional equivalent with enhanced 4-side shrouding.

Q: Can I use these parts interchangeably in existing designs?

A: Interchangeability depends on specific design requirements. Verify pitch compatibility with PCB footprints, confirm current rating adequacy for the application, and validate shroud configuration compatibility with mating connectors. All parts maintain 300V UL voltage rating and ROHS3 compliance, supporting direct substitution where mechanical and electrical specifications align.
