TE Connectivity AMP Connectors 640501-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 640501-2 is a rectangular connector header designed for through-hole mounting applications. This shrouded, 9-position connector with 4.2mm pitch operates across a temperature range of -55°C to 105°C and supports a current rating of 6A at 250VAC. The connector features male pin contacts with gold-plated mating surfaces and tin-lead post finishes, suitable for general-purpose board-to-cable/wire interconnections. The part is currently active in production. Identification of equivalent and substitute parts is necessary to address inventory availability, compliance requirements, and manufacturing continuity across different procurement channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers within the TE Connectivity AMP Connectors MR (Miniature Rectangular) series is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Number of positions (9)
• Number of rows (3)
• Pitch - mating (0.165" / 4.20mm)
• Row spacing - mating (0.165" / 4.20mm)
• Shrouding configuration (Shrouded - 4 Wall)
• Mounting type (Through Hole)
• Contact shape (Circular)

Electrical Compatibility Parameters:

• Contact type (Male Pin)
• Current rating (6A)
• Voltage rating (250VAC)
• Operating temperature range (-55°C ~ 105°C)
• Contact finish - mating (Gold)
• Contact material (Phosphor Bronze)

Manufacturing and Compliance Parameters:

• Termination method (Solder)
• Fastening type (Latch Lock)
• Insulation material (Polyamide / Nylon)
• Material flammability rating (UL94 V-0)

The substitute part 2-640501-2 maintains full equivalence across all mechanical and electrical parameters. The primary distinction between the main part and its substitute relates to post-finish composition (tin-lead versus tin) and regulatory compliance status (RoHS and REACH classifications).

Parameter Comparison

Engineering Selection Recommendations

The substitute part 2-640501-2 is a direct functional equivalent to 640501-2 across all mechanical and electrical parameters. Both parts are manufactured by TE Connectivity AMP Connectors and maintain identical specifications for connector configuration, contact geometry, current and voltage ratings, and operating temperature range.

The primary distinction between these parts is regulatory compliance status. The substitute part 2-640501-2 is ROHS3 compliant and REACH unaffected, whereas the main part 640501-2 is RoHS non-compliant and REACH affected. This difference reflects the post-finish composition: the substitute uses tin plating on the post contacts, while the main part uses tin-lead plating. Both post-finish specifications maintain the same thickness (150.0µin / 3.81µm) and provide equivalent electrical and mechanical performance.

Selection between these parts should be based on regulatory requirements applicable to the end application and geographic market. Applications subject to RoHS3 or REACH restrictions require the substitute part 2-640501-2. Applications without such restrictions may use either part. Both parts are active in production and available in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Are 640501-2 and 2-640501-2 mechanically interchangeable?

A: Yes. Both parts are identical in mechanical configuration, including number of positions (9), pitch (4.20mm), row spacing (4.20mm), shrouding (4-wall), mounting type (through-hole), and contact geometry (circular male pins). They are direct mechanical substitutes.

Q: Are 640501-2 and 2-640501-2 electrically interchangeable?

A: Yes. Both parts are identical in electrical specifications, including current rating (6A), voltage rating (250VAC), operating temperature range (-55°C to 105°C), contact material (phosphor bronze), and mating contact finish (gold plating at 30.0µin thickness). They are direct electrical substitutes.

Q: What is the difference between the post-finish specifications?

A: The main part 640501-2 uses tin-lead plating on the post contacts, while the substitute part 2-640501-2 uses tin plating. Both finishes are applied at the same thickness (150.0µin / 3.81µm) and provide equivalent solderability and electrical performance. The difference reflects compliance with RoHS3 regulations, which restrict lead content in electronic components.

Q: Which part should be selected for RoHS3-compliant applications?

A: The substitute part 2-640501-2 is ROHS3 compliant and must be selected for applications subject to RoHS3 requirements. The main part 640501-2 is RoHS non-compliant and is not suitable for such applications.

Q: Which part should be selected for REACH-restricted applications?

A: The substitute part 2-640501-2 is REACH unaffected and should be selected for applications subject to REACH restrictions. The main part 640501-2 is REACH affected and may not be suitable for such applications.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in bulk packaging. The substitute part 2-640501-2 has significantly higher inventory availability (32,700 pieces) compared to the main part 640501-2 (840 pieces).

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided that the design does not have specific regulatory compliance requirements that exclude one part or the other. The mechanical and electrical equivalence ensures functional interchangeability. Designs requiring RoHS3 or REACH compliance must use the substitute part 2-640501-2.

Q: What is the base product number for both parts?

A: Both parts share the base product number 640501. The main part is designated 640501-2, and the substitute is designated 2-640501-2. This nomenclature indicates variant specifications within the same product family.

Q: Are there any temperature or current derating considerations when substituting between these parts?

A: No. Both parts maintain identical operating temperature ranges (-55°C to 105°C) and current ratings (6A). No derating or thermal management adjustments are required when substituting between these parts.
