Phoenix Contact 1707421 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1707421 is a 2-position terminal block header with male pins, shrouded on all four sides, featuring a 0.150" (3.81mm) pitch for vertical through-hole mounting. This component is rated for 8A at 250V (IEC) and 300V (UL), with solder termination and UL94 V-0 flammability rating. The part is currently active in production and ROHS3 compliant.

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from multiple qualified manufacturers meeting identical or superior electrical and mechanical specifications.

Key Parameters

Parameter	Value
Number of Positions	2
Pitch	0.150" (3.81mm)
Header Orientation	Vertical
Type	Header, Male Pins, Shrouded (4 Side)
Termination Style	Solder
Mounting Type	Through Hole
Current Rating (UL)	8A
Voltage Rating (UL)	300V
Material Flammability Rating	UL94 V-0
RoHS Status	ROHS3 Compliant

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Number of positions: 2
Pitch: 0.150" (3.81mm)
Header orientation: Vertical
Type: Header, Male Pins, Shrouded (4 Side)
Termination style: Solder
Mounting type: Through Hole
Material flammability rating: UL94 V-0
RoHS compliance: ROHS3 Compliant

All four substitute parts meet these core criteria. Variations in current rating (8A vs. 10A), operating temperature range, housing material composition, and contact material do not preclude substitution when the application requirements fall within the specified limits of the substitute part.

Engineering Selection Recommendations

All four substitute parts are active products with ROHS3 compliance and UL94 V-0 flammability certification, meeting the core electrical and mechanical requirements of the Phoenix Contact 1707421.

Molex 0395111002 and 0395116002 are direct electrical equivalents with 8A current rating matching the primary part. The distinction between these two Molex variants is housing color (black vs. green), with no functional difference in electrical performance or mechanical compatibility.

Würth Elektronik 691321300002 and Amphenol Anytek OQ0232500000G both feature 10A current ratings, exceeding the 8A specification of the primary part. These parts are suitable for applications where the 8A rating is not a limiting constraint. The Amphenol part supports an extended operating temperature range of -40°C to 115°C compared to the Würth part's -40°C to 105°C range.

All parts share identical pitch, position count, shrouding configuration, and through-hole solder termination, ensuring mechanical and electrical interchangeability within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can Molex 0395111002 and 0395116002 be used interchangeably with the Phoenix Contact 1707421?

A: Yes. Both Molex parts are electrically and mechanically equivalent to the primary part, with identical pitch (3.81mm), position count (2), current rating (8A), voltage rating (300V), and flammability certification (UL94 V-0). The only difference is housing color, which does not affect functionality.

Q: Are the Würth Elektronik 691321300002 and Amphenol Anytek OQ0232500000G suitable substitutes despite their higher 10A current rating?

A: Yes. Both parts meet all core substitution criteria and exceed the 8A current requirement of the primary part. The higher current rating does not create incompatibility; it provides additional design margin. Selection depends on application requirements and supply availability.

Q: What is the significance of the different housing materials listed for these parts?

A: Housing material composition (Liquid Crystal Polymer vs. Polyamide vs. Thermoplastic Resin) does not affect electrical performance or mechanical compatibility when all parts share identical pitch, shrouding, and flammability ratings. Material selection is a manufacturing choice that does not impact substitution eligibility.

Q: Do all substitute parts maintain the same through-hole solder termination?

A: Yes. All listed parts use solder termination for through-hole mounting, ensuring compatibility with standard PCB assembly processes and existing board designs.

Q: Are there any compliance or certification differences between the primary part and substitutes?

A: All parts are ROHS3 compliant and carry UL94 V-0 flammability certification. The primary part is REACH Unaffected, while Würth Elektronik 691321300002 is REACH Affected. This distinction does not affect electrical or mechanical substitution but may be relevant for specific regulatory requirements in your application.
