Electrical Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 20
• Number of Rows: 1
• Voltage Rating: 250VAC
• Operating Temperature Range: -55°C ~ 105°C

Mechanical Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 1 Wall
• Fastening Type: Friction Lock

Material & Compliance Parameters:

• Contact Material: Copper Alloy
• Insulation Material: Thermoplastic
• Material Flammability Rating: UL94 V-0
• RoHS Compliance Status

The substitute part 2-640456-0 maintains equivalence across all critical electrical and mechanical parameters. The primary distinction is product status: the main part is obsolete while the substitute is active, with improved compliance documentation (ROHS3 Compliant versus RoHS Compliant).

Parameter Comparison

Engineering Selection Recommendations

The substitute part 2-640456-0 is functionally equivalent to the obsolete 5-641126-0 across all critical electrical and mechanical parameters. Selection of the substitute part is supported by the following factors:

Product Status: The substitute part maintains active product status, ensuring continued availability and manufacturing support. The main part's obsolete classification creates supply chain risk for new production and field repairs.

Compliance & Certifications: Both parts maintain UL94 V-0 material flammability rating and equivalent operating temperature ranges (-55°C ~ 105°C). The substitute part carries ROHS3 Compliant certification, representing current regulatory compliance standards compared to the main part's RoHS Compliant designation.

Electrical & Mechanical Equivalence: The substitute part preserves all critical specifications including 20-position, single-row configuration, 0.100" (2.54mm) pitch spacing, through-hole mounting, solder termination, and friction lock fastening. Contact geometry, material composition, and dimensional characteristics remain identical.

Packaging Consideration: The substitute part is supplied in bulk packaging, which may require adjustment to procurement and inventory management procedures compared to the main part's original packaging specification.

Frequently Asked Questions (FAQ)

Q: Can the 2-640456-0 substitute directly replace the 5-641126-0 in existing designs?

A: Yes. The substitute part maintains electrical and mechanical equivalence across all critical parameters including pitch spacing, position count, contact geometry, operating temperature range, and voltage rating. Direct substitution is supported without design modification.

Q: What is the primary reason for substitution?

A: The main part 5-641126-0 is classified as obsolete, creating supply chain discontinuity. The substitute part 2-640456-0 is active and maintains full functional equivalence, ensuring component availability for production and field service applications.

Q: Are there differences in contact finish between the two parts?

A: Yes. The main part features gold-plated mating contacts (15.0µin thickness) with tin-plated posts (150.0µin thickness). The substitute part features tin-plated mating contacts with tin-plated posts. Both configurations operate within the same electrical and thermal specifications. Contact finish selection should be evaluated based on application-specific corrosion resistance and signal integrity requirements.

Q: Does the bulk packaging of the substitute part affect compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. Bulk packaging may require adjustment to receiving inspection procedures, storage protocols, and inventory management systems. Component functionality and performance remain unchanged.

Q: Are both parts RoHS compliant?

A: Yes. The main part carries RoHS Compliant certification. The substitute part carries ROHS3 Compliant certification, representing current regulatory compliance standards. Both parts satisfy RoHS requirements for restricted substance elimination.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -55°C to 105°C, supporting applications in industrial, commercial, and consumer environments requiring extended thermal performance.

Q: Are there any differences in moisture sensitivity?

A: No. Both parts carry Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity constraints for storage, handling, or assembly processes.
