Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity AMP 3-1734798-0 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 30
• Pitch: 0.039" (1.00mm)
• Mounting Type: Surface Mount, Right Angle
• Contact Configuration: Bottom Contacts
• Termination Method: Solder
• FFC/FCB Thickness: 0.30mm
• Voltage Rating: 50V
• Current Rating: 0.5A
• Contact Material: Phosphor Bronze
• Flammability Rating: UL94 V-0

The Molex 0528523070 meets all mandatory matching parameters and qualifies as a direct substitute. Both connectors share identical electrical specifications, mechanical dimensions for critical interfaces, and material composition for contact surfaces. Variations in housing material (Thermoplastic, Glass Filled versus Polyphenylene Sulfide), contact finish composition (Tin versus Tin Bismuth), and height above board (3.20mm versus 3.10mm) remain within acceptable tolerance ranges for functional equivalence in FPC connector applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0528523070 is the qualified substitute for the obsolete TE Connectivity AMP 3-1734798-0. Selection of this substitute is supported by the following engineering factors:

Product Status Alignment: The TE Connectivity AMP 3-1734798-0 is obsolete, creating supply constraints. The Molex 0528523070 maintains active product status with documented inventory availability (1978 pieces in stock), ensuring long-term supply continuity.

Compliance and Certification: Both connectors carry UL94 V-0 flammability certification. The Molex 0528523070 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The TE Connectivity AMP part carries no RoHS applicability designation.

Electrical and Mechanical Equivalence: All critical electrical parameters (voltage, current, contact material) and mechanical specifications (pitch, position count, mounting configuration) are identical. Operating temperature ranges differ by 5°C (85°C versus 80°C maximum), with the Molex part operating within the TE Connectivity AMP specification envelope for standard industrial applications.

Physical Compatibility: Height above board variance (3.20mm versus 3.10mm) represents a 0.10mm difference within typical PCB design tolerances for surface-mount FPC connectors. Contact finish composition (Tin Bismuth versus Tin) provides equivalent solder wettability and reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0528523070 be used as a direct replacement for the TE Connectivity AMP 3-1734798-0 in existing designs?

A: Yes. The Molex 0528523070 meets all mandatory electrical and mechanical parameters. Both connectors feature 30 positions at 1.00mm pitch, bottom-contact configuration, surface-mount right-angle mounting, and identical voltage and current ratings. PCB layouts designed for the TE Connectivity AMP part accommodate the Molex substitute without modification.

Q: What is the significance of the 0.10mm height difference between these connectors?

A: The TE Connectivity AMP 3-1734798-0 measures 0.126" (3.20mm) above board, while the Molex 0528523070 measures 0.122" (3.10mm). This 0.10mm variance falls within standard PCB design tolerances for surface-mount FPC connectors and does not affect mechanical clearance or electrical performance in typical applications.

Q: Are there differences in contact finish that affect performance?

A: The TE Connectivity AMP part uses Tin contact finish; the Molex substitute uses Tin Bismuth. Both finishes provide equivalent solder wettability, electrical conductivity, and long-term reliability. Tin Bismuth offers enhanced corrosion resistance in certain environmental conditions.

Q: What is the operating temperature difference, and does it matter?

A: The TE Connectivity AMP 3-1734798-0 operates from -20°C to 85°C; the Molex 0528523070 operates from -20°C to 80°C. The Molex part operates within the TE Connectivity AMP specification range. Applications requiring operation above 80°C require design review.

Q: Why is the Molex part listed as active while the TE Connectivity AMP part is obsolete?

A: The TE Connectivity AMP 3-1734798-0 has been discontinued and is no longer manufactured. The Molex 0528523070 remains in active production with current inventory availability, making it the appropriate substitute for ongoing supply requirements.

Q: Are there packaging differences between these parts?

A: The TE Connectivity AMP 3-1734798-0 packaging is not specified in available documentation. The Molex 0528523070 is supplied in Tape & Reel (TR) format, standard for high-volume surface-mount connector applications.

Q: Do both connectors meet the same regulatory standards?

A: Both connectors carry UL94 V-0 flammability certification. The Molex 0528523070 is ROHS3 compliant and REACH unaffected. The TE Connectivity AMP part shows no RoHS applicability. For applications requiring RoHS compliance, the Molex substitute is the appropriate selection.

Q: What is the MSL rating for both connectors?

A: Both the TE Connectivity AMP 3-1734798-0 and Molex 0528523070 carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations for storage or handling.
