MS3475L12-8B Equivalent & Substitute Parts

Part Overview

The MS3475L12-8B is an 8-position circular connector plug housing manufactured by TE Connectivity Deutsch Connectors. This component is designed for free-hanging (in-line) applications with bayonet lock fastening and operates across a temperature range of -55°C to 200°C. The connector features a shielded aluminum alloy housing with electroless nickel finish and is classified as a military-grade component per MIL-DTL-26482 G Series II, AFD specifications.

The MS3475L12-8B is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design compatibility and ensure continued availability for applications requiring this connector specification.

Substitute Part Grouping Explanation

Substitute parts for the MS3475L12-8B are identified based on strict electrical and mechanical parameter equivalence. The following parameters must match exactly for a part to function as a direct substitute:

• Connector Type: Plug Housing
• Type: For Female Sockets
• Number of Positions: 8
• Shell Size - Insert: 12-8
• Contact Type: Crimp
• Contact Size: 20
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Orientation: N (Normal)
• Shell Material: Aluminum Alloy
• Shell Finish: Electroless Nickel
• Ingress Protection: Environment Resistant
• Insert Material: Plastic
• Contact Shape: Circular
• Operating Temperature: -55°C ~ 200°C

The PV76L12-8SL meets all critical mechanical and electrical parameters required for substitution. Differences in shielding configuration and product status are noted in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

The PV76L12-8SL is a functional equivalent to the MS3475L12-8B based on matching mechanical dimensions, electrical specifications, contact configuration, and operating temperature range. Both connectors share identical shell size (12-8), contact size (20), fastening mechanism (bayonet lock), and environmental protection ratings.

The primary distinction between these parts is the shielding configuration: the MS3475L12-8B is shielded, while the PV76L12-8SL is unshielded. This difference must be evaluated against application requirements. Applications requiring electromagnetic shielding should retain the shielded configuration; applications without shielding requirements can utilize the unshielded substitute.

The PV76L12-8SL maintains active product status, ensuring continued availability and supply chain stability compared to the discontinued MS3475L12-8B. Both parts are RoHS non-compliant and carry identical export classification (EAR99) and tariff codes (8538.90.8180).

Frequently Asked Questions (FAQ)

Q: Can the PV76L12-8SL directly replace the MS3475L12-8B in all applications?

A: The PV76L12-8SL matches all critical mechanical and electrical parameters of the MS3475L12-8B. The unshielded design of the PV76L12-8SL differs from the shielded MS3475L12-8B. Applications requiring electromagnetic shielding must evaluate whether the unshielded configuration meets performance requirements.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: connector type (plug housing), position count (8), shell size (12-8), contact size (20), mounting type (free hanging in-line), fastening type (bayonet lock), shell material (aluminum alloy), shell finish (electroless nickel), operating temperature range (-55°C to 200°C), and contact configuration (crimp, circular).

Q: Are there differences in packaging between these parts?

A: The MS3475L12-8B packaging is not specified in available documentation. The PV76L12-8SL is supplied in bulk packaging. Packaging requirements should be confirmed with the supplier based on application needs.

Q: Do both parts require contacts to be supplied separately?

A: Yes. Both the MS3475L12-8B and PV76L12-8SL are supplied as housings without contacts included. Contacts must be sourced separately and crimped into the housing.

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

A: Both the MS3475L12-8B and PV76L12-8SL operate across the temperature range of -55°C to 200°C, providing equivalent thermal performance for high-temperature and cryogenic applications.

Q: Are both parts compliant with RoHS regulations?

A: No. Both the MS3475L12-8B and PV76L12-8SL are RoHS non-compliant. Applications subject to RoHS requirements must identify alternative components that meet these compliance standards.

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

A: Both parts carry a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use.
