Phoenix Contact 1940897 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1940897 is a 2-position terminal block header with male pins, shrouded on 4 sides, designed for 0.200" (5.08mm) pitch vertical through-hole mounting. This component belongs to the COMBICON MSTBV series and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts from the active product portfolio is necessary to maintain design continuity and ensure ongoing component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1940897 is determined by strict alignment of the following critical parameters:

• Connector Type & Configuration: Header with male pins, shrouded on 4 sides
• Position Count & Pitch: 2 positions at 0.200" (5.08mm) pitch
• Orientation & Mounting: Vertical through-hole solder termination
• Electrical Ratings: IEC voltage and current specifications (400 V IEC, 12A IEC minimum)
• Compliance & Material Standards: UL94 V-0 flammability rating, RoHS compliance

The substitute part 1955633 meets these core substitution criteria. It maintains identical connector geometry, position count, pitch, orientation, and mounting method. Both parts are rated for 400 V IEC and UL94 V-0 material compliance. The substitute is from the active COMBICON CCV series, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1955633 is the qualified substitute for the obsolete 1940897 based on the following engineering criteria:

Product Status & Availability: The 1955633 is an active product from Phoenix Contact's current COMBICON CCV series, ensuring long-term availability and manufacturing support. The original 1940897 is obsolete and no longer in active production.

Electrical Compliance: Both parts meet IEC voltage and current specifications at 400 V and 12A IEC ratings. The 1955633 maintains UL compliance with a 300 V / 10 A UL rating, which is within acceptable parameters for most applications requiring the original part.

Material & Flammability Standards: Both parts carry UL94 V-0 flammability certification. The 1955633 uses Liquid Crystal Polymer (LCP) housing material instead of polyamide, which provides equivalent or superior performance characteristics while maintaining the same flammability rating.

Regulatory Compliance: The 1955633 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in industrial applications.

Physical Compatibility: Connector geometry, position count, pitch, orientation, and through-hole solder termination are identical between both parts. Insulation height differs by 0.008" (0.20mm), which is within acceptable mechanical tolerance for standard PCB mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the 1955633 be used as a direct replacement for the 1940897 in existing designs?

A: Yes. Both parts share identical connector type, position count, pitch, orientation, and termination method. Physical mounting and electrical interface compatibility are maintained. The 0.008" (0.20mm) difference in insulation height is within standard PCB tolerance ranges and does not affect functional compatibility.

Q: What is the difference in housing material between the two parts?

A: The 1940897 uses Polyamide (PA) Nylon, while the 1955633 uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements. LCP offers improved dimensional stability and chemical resistance compared to polyamide.

Q: Are there any electrical rating differences I should consider?

A: The IEC ratings are identical at 400 V and 12A. The UL rating for the 1955633 is 10 A compared to 12 A for the 1940897. For applications operating within 10 A UL specifications, the substitute is fully compatible. Applications requiring the full 12 A UL rating should be evaluated against the 10 A specification of the substitute.

Q: Is the 1955633 available in the same packaging as the 1940897?

A: The 1940897 was supplied in standard packaging (not specified). The 1955633 is available in bulk packaging. Consult with your supplier regarding packaging options and minimum order quantities for the substitute part.

Q: What is the contact tail length difference, and does it affect PCB mounting?

A: The 1940897 contact tail length is not specified in the data. The 1955633 has a contact tail length of 0.102" (2.60mm). Standard PCB through-hole mounting accommodates this specification without modification to existing PCB designs.

Q: Are both parts RoHS compliant?

A: Yes. The 1940897 is RoHS compliant. The 1955633 is ROHS3 compliant, which represents the current regulatory standard and ensures compliance with the latest RoHS directives.
