Key Parameters

Substitute Part Grouping Explanation

Substitution of the SP28W1G5 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part SP28W2G5 qualifies as a direct equivalent because it maintains identical specifications in the following key areas:

• Contact Configuration: Pin type, Size 20, stamped construction
• Wire Compatibility: 28-30 AWG (0.05 ~ 0.08mm²) wire gauge range
• Termination Method: Crimp termination
• Material Composition: Copper alloy contact material
• Surface Treatment: Gold finish at 5.00µin (0.127µm) thickness
• Functional Features: Insulation support
• Series Compatibility: ecomate® Aquarius™ series
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The primary distinction between the main part and substitute is product status (Obsolete vs. Active) and packaging format (bulk vs. Tape & Reel). These differences do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

SP28W2G5 is the direct substitute for SP28W1G5 in all applications requiring 28-30 AWG pin contacts with Size 20 crimp termination in the ecomate® Aquarius™ series.

Selection Basis:

• Electrical Equivalence: All electrical parameters are identical, including contact material, finish specification, and wire gauge compatibility.
• Mechanical Compatibility: Contact geometry, size, and termination method are identical, ensuring drop-in replacement capability.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and safety standards.
• Product Availability: SP28W2G5 holds Active product status with current manufacturing support, whereas SP28W1G5 is Obsolete. For new designs and ongoing procurement, SP28W2G5 is the appropriate selection.
• Packaging Consideration: SP28W2G5 is supplied in Tape & Reel format, which is standard for automated assembly operations. Bulk packaging availability should be confirmed with the supplier if required for manual assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SP28W2G5 be used as a direct replacement for SP28W1G5 in existing assemblies?

A: Yes. SP28W2G5 is electrically and mechanically equivalent to SP28W1G5. All contact specifications, wire gauge compatibility, and termination characteristics are identical. The parts are interchangeable in all applications.

Q: What is the difference between SP28W1G5 and SP28W2G5?

A: The parts are functionally identical. The differences are: (1) Product Status—SP28W1G5 is Obsolete while SP28W2G5 is Active; (2) Packaging—SP28W1G5 is supplied in bulk format while SP28W2G5 is supplied in Tape & Reel (TR) format. These differences do not affect electrical or mechanical performance.

Q: Why is SP28W1G5 marked as Obsolete?

A: Obsolete status indicates that the part is no longer in active production. SP28W2G5 is the current active equivalent and should be used for all new designs and ongoing procurement requirements.

Q: Is Tape & Reel packaging compatible with my assembly process?

A: Tape & Reel packaging is designed for automated pick-and-place assembly systems. If your process requires bulk packaging, contact the manufacturer to confirm alternative packaging availability for SP28W2G5 or to verify bulk supply options.

Q: Are there any compliance differences between SP28W1G5 and SP28W2G5?

A: No. Both parts are ROHS3 Compliant and REACH Unaffected. Regulatory compliance status is identical.

Q: What wire gauges are compatible with these contacts?

A: Both SP28W1G5 and SP28W2G5 are designed for 28-30 AWG wire, equivalent to 0.05 ~ 0.08mm² cross-sectional area. Wire gauge compatibility is identical between the two parts.

Q: Can these contacts be used with non-crimp termination methods?

A: No. Both parts are specified for crimp termination only. The contact design and material composition are optimized for crimp-style connections.
