Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the APK-PB25A40L is based on the following critical parameters:

Electrical Compatibility Criteria:

• Contact termination method (Crimp)
• Contact material (Copper Alloy base)
• Circular connector category classification
• Wire gauge accommodation range

Mechanical Compatibility Criteria:

• Stamped contact construction
• Insulation support feature presence
• Connector series interoperability

Compliance & Regulatory Criteria:

• ECCN classification (EAR99)
• HTSUS code alignment (8536.90.4000)

The identified substitute part 97-45-1622S-4(0920) shares the same termination method (Crimp), contact material (Copper Alloy), connector category (Circular Connectors), and regulatory classification. However, differences exist in wire gauge range, contact type (Socket vs. Pin), contact finish (Silver vs. Tin), and RoHS compliance status, which must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration – RoHS Compliance: The APK-PB25A40L is ROHS3 compliant, while the substitute part 97-45-1622S-4(0920) is RoHS non-compliant. Applications subject to RoHS3 regulatory requirements must use the main part or identify alternative compliant substitutes.

Secondary Consideration – Product Status: Both parts maintain active production status, ensuring continued availability and supply chain stability.

Wire Gauge Mismatch: The substitute part accommodates 16-22 AWG wire gauges, which does not overlap with the main part's 12-14 AWG specification. This represents a fundamental incompatibility for applications requiring the specified wire gauge range.

Contact Type Incompatibility: The main part is a pin contact, while the substitute is a socket contact. These are complementary contact types designed for mating pairs and are not interchangeable within the same connector assembly.

Contact Finish Difference: Tin finish (main part) and silver finish (substitute) provide different electrical and environmental performance characteristics. Selection depends on application-specific corrosion resistance and conductivity requirements.

Application Classification: The main part is classified for power applications, while the substitute is classified for signal applications, indicating different current and voltage handling capabilities.

Frequently Asked Questions (FAQ)

Q: Can the 97-45-1622S-4(0920) directly replace the APK-PB25A40L?

A: No. The substitute part differs in wire gauge range (16-22 AWG vs. 12-14 AWG), contact type (Socket vs. Pin), RoHS compliance status, and application classification (Signal vs. Power). Direct replacement is not supported.

Q: What does the wire gauge difference mean for compatibility?

A: Wire gauge determines the cross-sectional area of wire that the contact can accommodate. The main part accepts 12-14 AWG (2.5–4.0 mm²), while the substitute accepts 16-22 AWG. These ranges do not overlap, making the parts incompatible for the same wiring applications.

Q: Why is the contact type (Pin vs. Socket) important?

A: Pin and socket contacts are complementary components designed to mate with each other. A pin contact cannot replace a socket contact within the same connector assembly. The connector design specifies which contact type is required at each position.

Q: Does RoHS compliance affect substitution?

A: Yes. If the application or end-use market requires RoHS3 compliance, the non-compliant substitute part cannot be used. Regulatory requirements must be verified before selecting alternative components.

Q: Are both parts suitable for power applications?

A: The main part (APK-PB25A40L) is classified for power applications. The substitute part (97-45-1622S-4(0920)) is classified for signal applications, indicating different electrical performance specifications. Application requirements must determine which classification is appropriate.

Q: What is the significance of the contact finish (Tin vs. Silver)?

A: Contact finish affects electrical conductivity, corrosion resistance, and environmental performance. Tin provides cost-effective protection for general applications, while silver offers superior conductivity and corrosion resistance for demanding environments. Selection depends on application-specific environmental and electrical requirements.

Q: Are both parts currently available?

A: Yes. The main part has 1082 units in stock, and the substitute part has 1205 units in stock, both with active production status.
