Phoenix Contact 1941032 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1941032 is a 5-position terminal block header with male pins, shrouded on 4 sides, designed for 0.197" (5.00mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The part operates at 12A (IEC) / 12A (UL) and 400V (IEC) / 300V (UL), with solder termination and tin contact mating finish. Due to its obsolete status, sourcing active alternatives with compatible electrical and mechanical specifications is necessary for system continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1941032 is determined by strict alignment of the following critical parameters:

• Number of Positions and Pitch: Both must be 5 positions at 0.197" (5.00mm) pitch to ensure PCB footprint compatibility
• Header Type and Orientation: Must be male pins, shrouded (4 side), vertical orientation for mechanical fit
• Mounting Type: Through-hole mounting is required for solder termination compatibility
• Electrical Ratings: Current and voltage ratings must meet or exceed IEC and UL specifications (12A IEC, 400V IEC minimum; 12A UL, 300V UL minimum)
• Termination Style: Solder termination is mandatory for assembly process compatibility
• Contact Mating Finish: Tin finish ensures consistent solderability and contact reliability

The Phoenix Contact 1837051 (COMBICON CCVA series) meets all substitution criteria as an active product with identical mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1837051 is the direct active equivalent for the obsolete 1941032. Selection is based on the following engineering criteria:

Electrical Compatibility: The 1837051 maintains IEC current rating at 12A and exceeds UL current rating at 16A, providing margin above the original 12A specification. Voltage ratings align at 300V (UL) and 400V (IEC), meeting all electrical requirements.

Mechanical Compatibility: Both parts share identical pitch (5.00mm), position count (5), connector type (male pins, shrouded 4-side), and vertical through-hole mounting configuration. PCB footprint compatibility is assured.

Regulatory Compliance: The 1837051 carries ROHS3 Compliant and REACH Unaffected certifications, exceeding the RoHS Compliant status of the original part. Both parts maintain UL94 V-0 or equivalent flammability standards.

Product Status: The 1837051 is active in production, ensuring long-term availability and supply chain stability compared to the obsolete 1941032.

Physical Differences: The 1837051 features a shorter contact tail length (0.079" vs. 0.146") and uses Liquid Crystal Polymer (LCP) housing instead of Polyamide (PA). These differences do not affect electrical or mechanical compatibility in standard through-hole solder applications.

Frequently Asked Questions (FAQ)

Q: Can the 1837051 be used as a direct drop-in replacement for the 1941032?

A: Yes. Both parts share identical pitch (5.00mm), position count (5), connector type (male pins, shrouded 4-side), and vertical through-hole mounting. PCB footprint and assembly process compatibility are maintained.

Q: What is the difference in current rating between these parts?

A: The 1941032 is rated at 12A (UL). The 1837051 is rated at 16A (UL). The substitute exceeds the original specification, providing additional current capacity margin.

Q: Are there differences in housing material?

A: Yes. The 1941032 uses Polyamide (PA) housing, while the 1837051 uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements. LCP offers improved thermal and chemical resistance.

Q: Does the shorter contact tail length of the 1837051 affect compatibility?

A: No. The contact tail length difference (0.079" vs. 0.146") does not impact PCB hole engagement or solder joint formation in standard through-hole applications.

Q: What is the inventory status of these parts?

A: The 1941032 (obsolete) has 1006 pcs in stock. The 1837051 (active) has 897 pcs in stock. The active status of the 1837051 ensures continued availability.

Q: Are both parts RoHS compliant?

A: Yes. The 1941032 is RoHS Compliant. The 1837051 is ROHS3 Compliant, representing a higher compliance standard.
