Phoenix Contact 1941029 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1941029 is a 4-position terminal block header with male pins, shrouded on all four sides, designed for 0.197" (5.00mm) pitch vertical through-hole mounting. This component operates at 12A (IEC) / 12A (UL) and 400V (IEC) / 300V (UL), featuring tin-plated contacts and polyamide housing with UL94 V-0 flammability rating.

The 1941029 is classified as obsolete. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring this terminal block configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1941029 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (12A minimum), voltage rating (320V minimum for IEC), and contact mating finish (tin-plated)
• Mechanical Compatibility: 4-position configuration, 0.197" (5.00mm) pitch, vertical orientation, male pins with 4-side shrouding, through-hole mounting
• Material & Compliance: Polyamide housing, UL94 V-0 flammability rating, RoHS compliance

The substitute part 1837048 meets all critical electrical and mechanical parameters, with the exception of a lower IEC voltage rating (320V versus 400V). This part belongs to the COMBICON CCVA series and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1837048 serves as the active-status equivalent for the obsolete 1941029. Both components share identical mechanical configuration, current rating, and termination methodology. The primary design consideration is the voltage rating differential: the 1837048 operates at 320V (IEC) compared to the 1941029 at 400V (IEC).

Selection of the 1837048 is appropriate for applications operating at or below 320V (IEC). For applications requiring the full 400V (IEC) rating of the original 1941029, alternative sourcing or design modification may be necessary.

Both parts maintain RoHS compliance and tin-plated contact finishes, ensuring compatibility with standard PCB assembly processes and solder reflow profiles.

Frequently Asked Questions (FAQ)

Q: Can the 1837048 directly replace the 1941029 in all applications?

A: The 1837048 provides direct mechanical and electrical compatibility for applications operating at 320V (IEC) or below. Applications requiring the full 400V (IEC) rating of the 1941029 require voltage rating verification before substitution.

Q: What are the key differences between these two parts?

A: The primary difference is the IEC voltage rating: 1941029 operates at 400V, while 1837048 operates at 320V. Both maintain identical 4-position, 5.00mm pitch, vertical through-hole configuration with 12A current rating and tin-plated contacts.

Q: Are both parts RoHS compliant?

A: Yes. The 1941029 is RoHS Compliant, and the 1837048 is ROHS3 Compliant, both meeting current regulatory requirements.

Q: What is the packaging difference?

A: The 1941029 was supplied with unspecified packaging, while the 1837048 is supplied in bulk packaging.

Q: Why is the 1941029 obsolete?

A: The 1941029 has been discontinued by Phoenix Contact. The 1837048 represents the active-status alternative within the COMBICON terminal block family.
