Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers within the MTA-100 series is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 8
• Voltage Rating: 250VAC
• Contact Type: Male Pin
• Contact Material: Copper Alloy

Mechanical Compatibility Parameters:

• Connector Type: Header
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Friction Lock
• Shrouding: Shrouded - 1 Wall
• Number of Rows: 1
• Contact Shape: Square
• Overall Contact Length: 0.550" (13.97mm)
• Insulation Height: 0.347" (8.81mm)

Environmental & Compliance Parameters:

• Operating Temperature: -55°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• Insulation Material: Polybutylene Terephthalate (PBT), Glass Filled
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute part 3-647609-8 maintains full equivalence across all critical parameters with the exception of contact finish composition on mating and post surfaces, where tin-lead finish is replaced with tin finish. This variation does not affect functional compatibility or performance within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 647609-8 and 3-647609-8 are active production parts manufactured by TE Connectivity within the MTA-100 series. Selection between these parts is based on the following engineering criteria:

647609-8 (Main Part):

• RoHS Compliant status
• Tin-Lead contact finish composition
• 953 units currently in stock
• Suitable for applications requiring tin-lead plating specifications

3-647609-8 (Substitute Part):

• ROHS3 Compliant status, representing updated regulatory compliance
• Tin contact finish composition, eliminating lead content
• 1197 units currently in stock, providing greater availability
• Suitable for applications requiring lead-free contact finishes or updated RoHS3 compliance

Both parts maintain identical electrical performance, mechanical dimensions, and thermal operating characteristics. The contact finish difference (tin-lead versus tin) does not affect functional compatibility within the specified 250VAC, -55°C to 105°C operating envelope. Selection should be based on specific application requirements regarding contact finish composition and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Are the 647609-8 and 3-647609-8 electrically interchangeable?

A: Yes. Both parts operate at 250VAC with identical pitch (0.100"/2.54mm), 8-position configuration, and contact material (copper alloy). Electrical performance is equivalent across the specified operating temperature range of -55°C to 105°C.

Q: What is the difference between tin-lead and tin contact finishes?

A: The 647609-8 features tin-lead contact finish, while the 3-647609-8 features tin contact finish. Both finishes provide equivalent electrical conductivity and corrosion resistance within the specified operating parameters. The tin finish eliminates lead content, aligning with lead-free manufacturing standards.

Q: Can I use 3-647609-8 as a direct replacement for 647609-8 in existing designs?

A: Yes. The 3-647609-8 maintains full mechanical and electrical compatibility with the 647609-8. All critical dimensions, contact configurations, mounting specifications, and electrical ratings are identical. The contact finish difference does not affect functional performance.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: RoHS Compliant refers to the original Restriction of Hazardous Substances directive. ROHS3 Compliant indicates compliance with the updated RoHS 3 directive (2011/65/EU as amended by 2015/863/EU), which includes additional restricted substances. Both statuses indicate regulatory compliance; ROHS3 represents the current regulatory standard.

Q: Are both parts suitable for through-hole PCB assembly?

A: Yes. Both the 647609-8 and 3-647609-8 are designed for through-hole mounting with solder termination. Both feature identical post lengths (0.135"/3.43mm) and overall contact lengths (0.550"/13.97mm) for standard PCB thickness applications.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage or handling.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. Both parts operate across the temperature range of -55°C to 105°C. The insulation material (polybutylene terephthalate with glass fill) and UL94 V-0 flammability rating support operation throughout this range.

Q: What is the current rating for these connectors?

A: Current rating varies by wire gauge. The voltage rating is 250VAC. Specific current capacity depends on the wire gauge used in the mated cable assembly.

Q: Are these parts REACH compliant?

A: Yes. Both the 647609-8 and 3-647609-8 have REACH Unaffected status, indicating compliance with REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations.
