Molex 5042811300 FPC Connector - Equivalent & Substitute Parts

Part Overview

The Molex 5042811300 is a 13-position FPC (Flat Flexible) connector with 0.30mm pitch, designed for surface mount right-angle applications. This connector features top and bottom contacts for dual-sided FPC termination. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for FPC connectors is determined by the following critical parameters:

• Position Count: Must match at 13 positions
• Pitch: Must match at 0.30mm (0.012")
• Mounting Configuration: Must be surface mount, right-angle orientation
• Contact Type: The main part features top and bottom contacts; substitutes must accommodate the same FPC termination requirements
• Electrical Ratings: Voltage (50V) and current (0.3A minimum) must be met or exceeded
• Operating Temperature Range: Must support the required thermal envelope
• Compliance: RoHS3 compliance required for modern procurement

The identified substitute part (Molex 5035661302) shares the core mechanical and electrical parameters but differs in contact configuration (bottom contacts only) and certain performance specifications, requiring engineering evaluation for specific application compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Molex 5035661302 is an active product with current manufacturing support, providing supply chain continuity for the obsolete 5042811300. Both parts maintain ROHS3 compliance and identical pitch/position specifications.

Key considerations for substitution:

• The 5035661302 features bottom contacts only, whereas the 5042811300 provides top and bottom contact access. Application designs utilizing dual-sided contact termination require evaluation of single-contact-side compatibility.
• Current rating differs: 5035661302 is rated at 0.2A versus 0.3A for the main part. Applications requiring 0.3A operation must confirm the substitute meets load requirements.
• Operating temperature range extends to 105°C on the substitute versus 85°C on the main part, providing enhanced thermal margin.
• The 5035661302 includes a flip lock locking feature and solder retention, features not specified on the main part.

Frequently Asked Questions (FAQ)

Q: Can the 5035661302 directly replace the 5042811300 in all applications?

A: Direct replacement depends on application-specific requirements. Both parts share identical pitch (0.30mm), position count (13), and mounting configuration (surface mount, right angle). However, the contact configuration differs: the main part provides top and bottom contacts while the substitute provides bottom contacts only. Applications designed for dual-sided contact access require design modification or alternative sourcing.

Q: What is the impact of the lower current rating on the 5035661302?

A: The substitute is rated at 0.2A compared to 0.3A on the main part. Applications operating at or below 0.2A are unaffected. Designs requiring 0.3A operation must either source alternative parts or reduce circuit current requirements.

Q: Are both parts RoHS3 compliant?

A: Yes, both the 5042811300 and 5035661302 are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component procurement.

Q: What packaging is available for the 5035661302?

A: The 5035661302 is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Does the extended operating temperature range of the 5035661302 affect compatibility?

A: The 5035661302 supports -40°C to 105°C operation versus -40°C to 85°C for the main part. This extended range provides additional thermal margin and does not restrict compatibility with applications designed for the narrower temperature range of the original part.
