Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-66507-0 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series: AMPLIMITE HDP-20
• Pin or Socket: Pin
• Contact Termination: Crimp
• Wire Gauge: 24-28 AWG
• Contact Material: Brass
• Contact Finish: Gold
• Type: Stamped
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts maintain identical specifications across these parameters. Variations in packaging format (Bulk versus Cut Tape) and product status (Obsolete versus Active) do not affect electrical or mechanical compatibility. Contact finish thickness variations (Flash versus 30.0µin) represent manufacturing process differences within acceptable tolerance ranges for this contact classification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents):

The parts 1658540-1, 1658540-4, and 66507-4 are direct functional equivalents to the 1-66507-0. All three maintain identical electrical and mechanical specifications across wire gauge, contact termination, material composition, and finish type.

Active Product Status Advantage:

Parts 1658540-1, 1658540-4, and 66507-4 carry Active product status, ensuring continued manufacturer support, availability, and compliance updates. The 1-66507-0 is classified as Obsolete and should be replaced in new designs and procurement cycles.

RoHS Compliance Consideration:

Parts 1658540-1 and 1658540-4 are ROHS3 compliant, representing the latest regulatory standard. Part 66507-4 maintains RoHS compliance. Both compliance levels satisfy current environmental regulations for electronic components.

Packaging and Inventory:

Selection between substitute parts should consider packaging requirements and inventory availability. Cut Tape (CT) packaging is standard for active production environments. Part 1658540-1 offers the highest inventory level (183,105 pcs), providing supply chain stability. Part 1658540-4 offers enhanced contact finish thickness (30.0µin) at reduced inventory levels (2,300 pcs). Part 66507-4 provides intermediate inventory availability (73,596 pcs) with standard flash finish.

Contact Finish Thickness:

Part 1658540-4 specifies 30.0µin (0.76µm) gold plating thickness, compared to Flash finish on 1-66507-0, 1658540-1, and 66507-4. This specification difference reflects manufacturing process variation and does not affect functional compatibility within the AMPLIMITE HDP-20 series.

Frequently Asked Questions (FAQ)

Q: Can 1658540-1, 1658540-4, and 66507-4 be used interchangeably with 1-66507-0?

A: Yes. All three parts maintain identical specifications for wire gauge (24-28 AWG), contact termination (Crimp), contact material (Brass), contact finish (Gold), and series compatibility (AMPLIMITE HDP-20). Packaging format differences (Bulk versus Cut Tape) do not affect electrical or mechanical performance.

Q: What is the difference between Flash finish and 30.0µin gold plating?

A: Flash finish represents a thin, minimal gold coating applied to the contact surface. The 30.0µin (0.76µm) specification on part 1658540-4 defines a measurable plating thickness. Both finishes provide corrosion resistance and electrical conductivity suitable for AMPLIMITE HDP-20 applications. Selection depends on specific application requirements and environmental exposure conditions.

Q: Why is the 1-66507-0 classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. Active equivalents (1658540-1, 1658540-4, 66507-4) should be specified for new designs and ongoing procurement to ensure long-term availability and compliance with current standards.

Q: Does packaging format affect compatibility?

A: No. Bulk and Cut Tape (CT) packaging formats contain identical components. Packaging selection is determined by assembly process requirements, automation compatibility, and inventory management practices. Electrical and mechanical specifications remain unchanged regardless of packaging format.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 1-66507-0 is RoHS Compliant. Parts 1658540-1 and 1658540-4 are ROHS3 Compliant (latest standard). Part 66507-4 is RoHS Compliant. All parts satisfy current environmental regulations for electronic component manufacturing and use.

Q: Which substitute part should be selected for new production?

A: Part selection depends on specific requirements. For maximum inventory availability and ROHS3 compliance, specify 1658540-1. For enhanced contact finish thickness with ROHS3 compliance, specify 1658540-4. For standard specifications with high inventory availability, specify 66507-4. All three parts are functionally equivalent to the obsolete 1-66507-0.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. Storage, handling, and assembly do not require controlled humidity environments or baking procedures. All substitute parts maintain MSL 1 classification, ensuring identical environmental handling requirements.
