Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 208403-1 with the active equivalent 3-208403-2 is based on strict electrical and mechanical parameter alignment. Both connectors share identical core specifications: 10-position configuration, 0.200" (5.08mm) mating pitch, through-hole right-angle mounting, male pin contact type, 4-wall shrouding, 7.5A current rating, 600V voltage rating, and -55°C to 130°C operating temperature range. Both connectors utilize polyamide nylon insulation with UL94 V-0 flammability rating and feature copper alloy contacts with tin-lead or tin finish options.

The primary distinction between these parts is product status and regulatory compliance. The 208403-1 is obsolete with tin-lead contact finish and RoHS non-compliant status. The 3-208403-2 is an active product with tin contact finish and ROHS3 compliant status, making it the direct functional and regulatory equivalent for new designs and ongoing production requirements.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 3-208403-2 is the direct equivalent substitute for the obsolete 208403-1. Selection of the 3-208403-2 is based on the following engineering criteria:

Product Status and Availability: The 3-208403-2 maintains active product status with 995 pieces in stock, ensuring reliable component availability for production and service applications. The 208403-1 is obsolete with limited remaining inventory.

Regulatory Compliance: The 3-208403-2 is ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components in automotive, industrial, and general purpose applications. The 208403-1 is RoHS non-compliant, presenting regulatory constraints for new designs and markets with RoHS mandates.

Electrical and Mechanical Compatibility: Both connectors maintain identical electrical ratings (7.5A, 600V), mechanical configuration (10-position, 0.200" pitch, through-hole right-angle), contact geometry (0.120" post length, 0.550" insulation height), and thermal operating range (-55°C to 130°C). These parameters ensure direct functional interchangeability in existing circuit designs.

Contact Finish Consideration: The 3-208403-2 features tin contact finish compared to tin-lead finish on the 208403-1. Tin finish is compatible with lead-free solder processes and provides equivalent electrical performance and corrosion resistance for the specified applications and operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the 3-208403-2 directly replace the 208403-1 in existing designs?

A: Yes. The 3-208403-2 is a direct functional equivalent with identical electrical ratings, mechanical dimensions, mounting configuration, and contact geometry. Both connectors are 10-position headers with 0.200" (5.08mm) pitch, through-hole right-angle mounting, and 7.5A/600V ratings. The connectors are mechanically and electrically interchangeable in all applications.

Q: What is the difference between the tin-lead finish on the 208403-1 and the tin finish on the 3-208403-2?

A: The 208403-1 uses tin-lead contact finish, while the 3-208403-2 uses tin finish. Tin finish is compatible with lead-free solder processes and RoHS compliance requirements. Both finishes provide equivalent electrical conductivity and corrosion resistance for the specified operating temperature range (-55°C to 130°C) and environmental conditions in automotive, industrial, and general purpose applications.

Q: Why is the 208403-1 listed as obsolete?

A: The 208403-1 is obsolete due to its RoHS non-compliant status and tin-lead contact finish. The 3-208403-2 represents the current active product offering with ROHS3 compliance and tin finish, meeting modern regulatory requirements and environmental standards.

Q: Are there packaging differences between the 208403-1 and 3-208403-2?

A: The 3-208403-2 is supplied in tube packaging. Packaging format does not affect electrical or mechanical performance and is determined by inventory and distribution requirements.

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

A: Substitution compatibility is determined by: connector type (header), number of positions (10), mating pitch (0.200"/5.08mm), mounting type (through-hole right-angle), contact type (male pin), shrouding configuration (4-wall), current rating (7.5A), voltage rating (600V), operating temperature range (-55°C to 130°C), and insulation material (polyamide nylon). Both the 208403-1 and 3-208403-2 meet all these parameters identically.

Q: Is the 3-208403-2 suitable for automotive applications?

A: Yes. The 3-208403-2 is rated for automotive, general purpose, and industrial applications. It meets UL94 V-0 flammability requirements and maintains operating specifications across the -55°C to 130°C temperature range required for automotive environments.

Q: What is the moisture sensitivity level for the 3-208403-2?

A: The 3-208403-2 has a moisture sensitivity level (MSL) of 1 (Unlimited), indicating no moisture sensitivity constraints for storage, handling, or assembly processes.
