Phoenix Contact 1915149 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915149 is a 10-position terminal block header with male pins, shrouded on four sides, designed for 0.197" (5.00mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The part operates at 12A (IEC) / 12A (UL) and 320V (IEC) / 300V (UL), with press-fit termination and UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1915149 is determined by strict alignment of the following critical parameters:

• 10-position configuration with 0.197" (5.00mm) pitch
• Vertical through-hole mounting orientation
• Header type with male pins and four-side shrouding
• Minimum current rating of 12A (IEC) and 12A (UL)
• Minimum voltage rating of 320V (IEC) and 300V (UL)
• UL94 V-0 flammability compliance
• Tin contact mating finish
• Matching insulation height of 0.472" (12.00mm)

The two identified substitutes meet these core electrical and mechanical requirements. Variations in termination style (press-fit versus solder), housing material composition, contact tail length, and product status are secondary considerations that do not preclude functional equivalence within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 1776964 and 1837446 satisfy the electrical and mechanical requirements of the obsolete 1915149. Selection between them depends on application-specific constraints:

Phoenix Contact 1776964 (COMBICON MSTBV Series): This active-status component provides direct electrical equivalence with enhanced voltage rating (400V IEC versus 320V IEC). The solder termination style requires PCB integration modification from the original press-fit design. Housing material remains PBT with UL94 V-0 compliance. This option is suitable for applications where solder-based assembly is standard practice and where the higher IEC voltage rating provides design margin.

Phoenix Contact 1837446 (COMBICON CCV Series): This active-status component offers elevated current rating (16A UL versus 12A UL) and operates across the specified temperature range (-40°C to 100°C). Housing material is Liquid Crystal Polymer (LCP) with UL94 V-0 compliance. Solder termination is required. This option is suitable for applications requiring higher current capacity or extended temperature operation.

Both substitutes carry active product status and full compliance certifications, eliminating obsolescence risk associated with the original part.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1776964 directly replace 1915149 in existing designs?

A: Electrical compatibility is confirmed across all rated parameters. However, termination style differs (solder versus press-fit), requiring PCB design modification. Mechanical footprint and pin spacing remain identical at 0.197" (5.00mm) pitch with 10 positions.

Q: What is the primary difference between 1776964 and 1837446?

A: Both are solder-terminated alternatives. Part 1776964 maintains PBT housing material and matches the original voltage ratings. Part 1837446 uses LCP housing, provides higher UL current rating (16A), and specifies operating temperature range (-40°C to 100°C). Housing material and current capacity are the distinguishing factors.

Q: Are there compliance or certification differences between the three parts?

A: All three parts carry UL94 V-0 flammability rating and tin contact mating finish. Parts 1776964 and 1837446 are active products with documented compliance status. The original 1915149 is obsolete. No compliance gaps exist between the substitutes and the original part.

Q: Does the contact tail length difference between 1915149 (3.90mm) and 1837446 (2.00mm) affect compatibility?

A: Contact tail length affects PCB hole depth and solder joint formation. The shorter tail on 1837446 requires verification against PCB design specifications. This parameter should be evaluated during design transition planning.

Q: Which substitute is recommended for new designs?

A: Both active-status substitutes are suitable for new designs. Selection depends on termination preference (both require solder), housing material requirements, and current/temperature specifications. Part 1837446 offers higher current capacity and temperature range specification, making it suitable for demanding applications.
