Phoenix Contact 1915246 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915246 is a 5-position terminal block header with male pins, shrouded on 4 sides, featuring 0.200" (5.08mm) pitch vertical through-hole mounting. This component is part of the COMBICON EMSTBV series and is classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is essential for ongoing design support, maintenance, and production continuity. Substitute parts must maintain electrical performance and mechanical compatibility while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Electrical Compatibility: Current rating (IEC) of 12A and voltage rating (IEC) minimum of 320V
• Mechanical Compatibility: 5 positions, 0.200" (5.08mm) pitch, vertical orientation, through-hole mounting, shrouded 4-side design
• Regulatory Compliance: UL94 V-0 flammability rating and RoHS compliance status

The substitute parts 1777109 and 1792766 meet these core requirements. Variations in termination style (press-fit vs. solder), housing material, contact tail length, and voltage ratings above the minimum threshold do not preclude substitution when the primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

1777109 (COMBICON MSTBV Series)

Part 1777109 is the primary substitute for 1915246. Both components share identical mechanical dimensions (5 positions, 0.200" pitch, 0.154" contact tail length, 0.472" insulation height) and electrical ratings (12A IEC current). The key difference is termination style: 1777109 uses solder termination versus the press-fit design of 1915246. Part 1777109 offers active product status, higher IEC voltage rating (630V vs. 320V), and ROHS3 compliance, making it suitable for new designs and production continuity. The solder termination requires PCB design accommodation but provides robust mechanical connection.

1792766 (COMBICON CCV Series)

Part 1792766 serves as an alternative substitute with active product status and ROHS3 compliance. This component maintains the 5-position, 0.200" pitch, vertical through-hole configuration and 12A IEC current rating. Differences include: shorter contact tail length (0.102" vs. 0.154"), different housing material (Liquid Crystal Polymer vs. PBT), black color instead of green, lower UL current rating (10A vs. 12A), and inclusion of a locking ramp feature. The reduced contact tail length requires PCB layout verification. Part 1792766 is suitable when the shorter tail length and locking ramp feature align with application requirements.

Selection Basis

Both substitute parts maintain compliance with UL94 V-0 flammability requirements and MSL 1 moisture sensitivity levels. The choice between 1777109 and 1792766 depends on PCB design constraints (contact tail length), termination process capability (solder vs. press-fit), and mechanical feature requirements (locking ramp).

Frequently Asked Questions (FAQ)

Q: Can 1777109 directly replace 1915246 in existing designs?

A: Mechanical and electrical compatibility is confirmed for the core terminal block function. The primary design consideration is termination style: 1915246 uses press-fit termination while 1777109 requires solder termination. PCB footprint and assembly process must be verified before implementation.

Q: What is the significance of the contact tail length difference in 1792766?

A: The contact tail length (0.102" for 1792766 vs. 0.154" for 1915246) affects PCB hole depth and component insertion depth. Designs using 1792766 must verify that the shorter tail length is compatible with the PCB thickness and through-hole specifications.

Q: Are there voltage rating differences that affect substitution?

A: All substitute parts exceed the minimum IEC voltage requirement of 320V (1777109: 630V, 1792766: 400V). The UL voltage rating remains 300V across all parts. Substitution is valid for applications within these voltage specifications.

Q: Does the housing material change affect performance?

A: 1915246 and 1777109 use PBT housing, while 1792766 uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements. Material selection may affect thermal performance and mechanical rigidity in specific applications; design verification is recommended for high-temperature or high-stress environments.

Q: What is the impact of the locking ramp feature in 1792766?

A: The locking ramp feature in 1792766 provides additional mechanical retention. This feature does not prevent substitution but may require connector design verification to ensure compatibility with mating components.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part 1915246 is RoHS Compliant. Both substitute parts (1777109 and 1792766) are ROHS3 Compliant, meeting current regulatory requirements.
