Phoenix Contact 1915301 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915301 is an 11-position terminal block header with male pins, shrouded on four sides, designed for 0.200" (5.08mm) pitch vertical through-hole mounting. This component belongs to the COMBICON EMSTBV series and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts with compatible electrical and mechanical specifications is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1915301 is determined by the following critical parameters:

• Position Count & Pitch: Must be 11 positions at 0.200" (5.08mm) pitch
• Header Type & Orientation: Must be male pins, shrouded (4 side), vertical orientation
• Mounting Method: Must be through-hole compatible
• Electrical Ratings: Must meet or exceed IEC and UL current and voltage specifications
• Physical Compatibility: Contact tail length and insulation height must accommodate existing PCB designs
• Housing Material & Flammability: UL94 V-0 rating required for safety compliance

The identified substitute parts (1777167 and 1792821) share the core mechanical and electrical characteristics with the main part. However, variations exist in termination style, voltage ratings, current ratings, housing material, and contact tail length, which must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1777167 is an active-status substitute with identical mechanical dimensions (contact tail length 0.154", insulation height 0.472") and electrical ratings (12A IEC, 300V UL). The primary difference is termination style: this part uses solder termination instead of press-fit. The IEC voltage rating is elevated to 630V, providing additional margin. Housing material remains PBT with UL94 V-0 compliance. This part is ROHS3 compliant and carries MSL 1 rating, suitable for modern manufacturing environments.

Phoenix Contact 1792821 is an active-status substitute with the same position count and pitch but introduces material and dimensional variations. The housing material is Liquid Crystal Polymer (LCP) instead of PBT, and the contact tail length is reduced to 0.102" (2.60mm). The UL current rating is 10A, which is lower than the main part's 12A specification. The IEC voltage rating is 400V. This part includes a locking ramp feature and is available in black color. RoHS compliance is confirmed, and MSL rating is 1.

Selection between substitutes depends on PCB design constraints (contact tail length compatibility), termination process capability (solder vs. press-fit), and electrical margin requirements. Both substitutes maintain UL94 V-0 flammability compliance and are actively manufactured.

Frequently Asked Questions (FAQ)

Q: Can 1777167 be used as a direct replacement for 1915301?

A: 1777167 shares identical mechanical dimensions and electrical ratings with 1915301. The primary difference is termination style: 1777167 uses solder termination while 1915301 uses press-fit. Direct substitution is possible if the PCB design accommodates solder termination and the manufacturing process supports this method.

Q: What is the impact of the shorter contact tail length on 1792821?

A: 1792821 has a contact tail length of 0.102" (2.60mm) compared to 1915301's 0.154" (3.90mm). This shorter tail may affect PCB hole depth requirements and solder joint formation. PCB design review is necessary to confirm compatibility with existing through-hole specifications.

Q: Are both substitute parts RoHS compliant?

A: Yes. 1777167 is ROHS3 compliant, and 1792821 is RoHS compliant. Both meet current environmental regulations for electronic component manufacturing.

Q: What is the significance of the different housing materials?

A: 1915301 and 1777167 use Polybutylene Terephthalate (PBT), while 1792821 uses Liquid Crystal Polymer (LCP). Both materials carry UL94 V-0 flammability ratings. LCP offers superior thermal and chemical resistance, but material selection should align with application environmental conditions and assembly process requirements.

Q: Does the elevated IEC voltage rating on 1777167 affect compatibility?

A: No. The 630V IEC rating on 1777167 exceeds the 320V specification of 1915301, providing additional safety margin. This is a beneficial characteristic for applications operating at or below the original voltage specification.

Q: What is the difference in current rating between 1792821 and the main part?

A: 1792821 has a UL current rating of 10A, while 1915301 is rated for 12A. Applications requiring the full 12A capacity must use 1915301 or 1777167. For applications operating below 10A, 1792821 is suitable.

Q: Are all three parts available in the same color?

A: No. 1915301 and 1777167 are green, while 1792821 is black. Color selection may be relevant for visual identification or assembly documentation purposes.
