Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Primary Matching Criteria:

Number of positions: 8
Header orientation: Vertical
Termination style: Solder
Mounting type: Through hole
Shroud configuration: 4-side shrouded
Pitch: 0.200" (5.08mm) or 0.197" (5.00mm) equivalent

Secondary Compatibility Factors:

Current rating: Minimum 12A (UL) or 12A (IEC)
Voltage rating: Minimum 300V (UL) or 400V (IEC)
Material flammability: UL94 V-0
Contact mating finish: Tin or Gold

Engineering Selection Recommendations

Direct Phoenix Contact Replacement (Preferred for Series Continuity):

Phoenix Contact 1955918 (COMBICON CCVA series) is the active equivalent with 4-side shrouding matching the original 1902877 configuration. This part maintains Phoenix Contact ecosystem compatibility and carries active product status with ROHS3 compliance. The 10A UL current rating is lower than the original 12A specification; applications requiring the full 12A rating should reference alternative options.

Cross-Manufacturer Alternatives (Molex Eurostyle ESE 39531 Series):

Molex 0395311008 and 0395314008 provide direct electrical and mechanical equivalence with 4-side shrouding, 5.08mm pitch, and 8 positions. Both parts exceed the original current specification at 15A UL and maintain 300V UL voltage rating. These parts are in active production with ROHS3 compliance and higher inventory availability. The 0395311008 features tin contact finish matching the original; 0395314008 supports extended operating temperature range (-40°C to 140°C).

Alternative Pitch Consideration (5.00mm vs 5.08mm):

Molex 0395211008 and HARTING 14120816001000 operate at 5.00mm pitch (0.197") versus the original 5.08mm (0.200"). These parts are electrically and mechanically compatible for applications where PCB layout permits 0.008" pitch tolerance. HARTING 14120816001000 provides enhanced voltage rating at 600V UL.

Product Status Compliance:

All substitute parts listed carry active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The original 1902877 obsolete status necessitates transition to one of these active alternatives for new designs or ongoing procurement.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1758076 (2-side shroud) replace the 1902877 (4-side shroud)?

A: 1758076 is electrically equivalent but features 2-side shrouding versus the original 4-side configuration. Substitution is valid only if the reduced shroud coverage meets application requirements for EMI shielding and mechanical protection.

Q: What is the pitch difference between 5.08mm and 5.00mm terminal blocks?

A: The 0.008" (0.20mm) difference represents a tolerance variation. Molex Eurostyle parts at 5.00mm pitch are mechanically compatible with 5.08mm PCB layouts within standard manufacturing tolerances. Verify PCB footprint acceptance before design implementation.

Q: Why does Phoenix Contact 1955918 have a lower current rating (10A vs 12A)?

A: The 1955918 uses Liquid Crystal Polymer (LCP) housing material versus polyamide in the original, resulting in different thermal and electrical characteristics. The 10A UL rating is the specified maximum for this material composition. Applications requiring 12A continuous current should select Molex alternatives rated at 15A.

Q: Are Molex Eurostyle parts suitable for direct PCB replacement?

A: Yes. Molex 0395311008 and 0395314008 maintain identical 5.08mm pitch, 8-position configuration, and through-hole solder termination. Pin-to-pin spacing and mounting hole patterns are compatible with the original 1902877 footprint.

Q: What is the difference between tin and gold contact finishes?

A: Molex 0395311508 features gold plating on contacts, providing enhanced corrosion resistance and lower contact resistance compared to tin finish. Gold-plated contacts are specified for high-reliability applications; tin finish (0395311008, 0395314008) is standard for general industrial use.

Q: Does HARTING 14120816001000 offer advantages over Molex alternatives?

A: HARTING 14120816001000 provides 600V UL voltage rating versus 300V in Molex parts, supporting higher-voltage applications. Operating temperature range is -40°C to 110°C. The 5.00mm pitch requires PCB footprint verification. Contact material is copper alloy versus brass in Molex parts.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting current regulatory requirements for lead-free and restricted substance elimination.
