SS28W1G5 Equivalent & Substitute Parts

Part Overview

The SS28W1G5 is a socket contact from Amphenol Sine Systems Corp's ecomate® RM series, designed for 28-30 AWG wire applications in Size 20 crimp terminations. This component is classified as Obsolete, necessitating identification of suitable alternatives to maintain supply chain continuity and support ongoing system requirements. The obsolete status requires engineers to evaluate available substitute parts that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS28W1G5 are qualified based on the following critical parameters that ensure functional compatibility:

Wire Gauge Compatibility: All substitutes must accommodate 28-30 AWG (0.05 ~ 0.08 mm²) wire sizes. This parameter determines the contact bore and crimp barrel dimensions.

Contact Size: Substitutes must maintain Size 20 contact designation to ensure physical and electrical compatibility with mating connector shells.

Termination Method: All qualified substitutes use crimp termination, consistent with the original part specification.

Contact Material & Finish: Copper alloy construction with gold plating at 5.00 µin thickness maintains electrical conductivity and corrosion resistance across substitutions.

Environmental Compliance: RoHS3 compliance and REACH unaffected status are maintained across all substitutes to support regulatory requirements.

The SS28W2G5 meets all these critical parameters while offering the advantage of Active product status and modern packaging (Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

SS28W2G5 (Active Substitute): This part is the qualified substitute for the obsolete SS28W1G5. Both components share identical electrical and mechanical parameters, ensuring direct compatibility. The SS28W2G5 offers the strategic advantage of Active product status, providing long-term availability and supply chain stability. Tape & Reel packaging offers manufacturing efficiency for high-volume applications. RoHS3 compliance and REACH unaffected status maintain regulatory alignment across both product lifecycles.

For new designs or component replenishment, SS28W2G5 is the appropriate selection. Existing inventories of SS28W1G5 remain electrically and mechanically compatible with systems designed for this contact type.

Frequently Asked Questions (FAQ)

Q: Can SS28W2G5 be used in place of SS28W1G5? A: Yes. Both parts have identical contact size (20), wire gauge range (28-30 AWG), termination method (crimp), material composition (copper alloy), and gold plating specification (5.00 µin). The electrical and mechanical interfaces are equivalent.

Q: What is the primary difference between these parts? A: The SS28W2G5 belongs to the ecomate® Aquarius™ series and maintains Active product status, whereas the SS28W1G5 is from the ecomate® RM series and is Obsolete. The substitute offers improved long-term supply availability.

Q: Does packaging affect compatibility? A: No. The SS28W2G5 is supplied in Tape & Reel (TR) packaging, which is a manufacturing and logistics specification that does not affect the electrical or mechanical properties of the contact itself. The contact performance and dimensional specifications remain constant regardless of packaging format.

Q: Are both parts RoHS3 compliant? A: Yes. Both SS28W1G5 and SS28W2G5 are RoHS3 compliant and REACH unaffected, meeting current environmental regulatory requirements.

Q: What wire gauges do these contacts support? A: Both contacts are rated for 28-30 AWG wire (0.05 ~ 0.08 mm²). The Size 20 contact bore is dimensioned for this wire range.
