Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 207830-4 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 50
• Number of rows: 3
• Shell size and layout: 5 (DD, D)
• Mounting type: Through Hole
• Termination method: Solder
• Connector style: D-Sub

Electrical Compatibility Parameters:

• Current rating: 6A (minimum requirement)
• Voltage rating: 125V (minimum requirement)
• Operating temperature range: -55°C ~ 105°C (minimum requirement)

Mechanical Compatibility Parameters:

• Contact material: Phosphor Bronze or equivalent
• Contact finish: Gold
• Flange feature: Housing/Shell (Unthreaded)

Substitute parts must satisfy all critical matching parameters and meet or exceed all electrical and mechanical requirements. Parts that deviate from these specifications are not suitable for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5745191-7 (Primary Substitute)

The 5745191-7 is the primary substitute for the obsolete 207830-4. This part maintains identical electrical and mechanical specifications, including 6A current rating, 125V voltage rating, and -55°C ~ 105°C operating temperature range. Both parts use phosphor bronze contacts with gold finish and feature the same 50-position, 3-row D-Sub configuration with through-hole solder termination. The 5745191-7 is classified as active product status with RoHS compliance, making it suitable for new designs and legacy system replacements. The part is available in tube packaging with 1875 units in stock.

TE Connectivity M24308/23-11F (Alternative Substitute)

The M24308/23-11F is an alternative substitute derived from the military specification MIL-DTL-24308 series. This part satisfies all critical mechanical matching parameters and maintains the same connector configuration. However, the current rating is specified at 5A, which is below the 6A rating of the main part. The voltage rating is not specified in the provided data. The operating temperature range extends to 125°C, exceeding the main part specification. This part uses brass contacts instead of phosphor bronze and features cadmium-plated steel shell material. The M24308/23-11F is classified as active product status with RoHS non-compliance and REACH affected status. This part is suitable for applications where military specification compliance and extended temperature operation are required, provided the 5A current limitation is acceptable.

Selection Criteria:

For direct replacement in existing systems, the 5745191-7 is the recommended choice due to matched electrical specifications and active product status. The M24308/23-11F is suitable for military or aerospace applications where MIL-DTL-24308 compliance is mandated, with the understanding that current rating and material composition differ from the original part.

Frequently Asked Questions (FAQ)

Q: Can the 5745191-7 be used as a direct replacement for the 207830-4?

A: Yes. The 5745191-7 matches all critical mechanical parameters (50 positions, 3 rows, shell size 5, through-hole solder termination) and meets or exceeds all electrical specifications (6A current, 125V voltage, -55°C ~ 105°C operating range). Both parts use phosphor bronze contacts with gold finish and unthreaded housing shells. The primary difference is product status: the 207830-4 is obsolete while the 5745191-7 is active.

Q: What are the differences between the 5745191-7 and M24308/23-11F?

A: Both parts share the same mechanical configuration and connector type. Key differences include: current rating (5745191-7 is 6A versus M24308/23-11F at 5A), contact material (phosphor bronze versus brass), shell material finish (not specified versus cadmium-plated steel), and product lineage (commercial AMPLIMITE HD-20 versus military MIL-DTL-24308). The M24308/23-11F operates at higher temperature (-55°C ~ 125°C) and carries military specification compliance.

Q: Is the 5745191-7 RoHS compliant?

A: Yes. The 5745191-7 is RoHS compliant, whereas the original 207830-4 is RoHS non-compliant. This makes the 5745191-7 suitable for applications requiring RoHS compliance.

Q: Can the M24308/23-11F be used in applications requiring 6A current?

A: No. The M24308/23-11F is rated for 5A maximum current, which is below the 6A requirement of the original 207830-4. Use of this part in 6A applications would exceed its current rating specification.

Q: What is the difference in packaging between these parts?

A: The 207830-4 packaging is not specified. The 5745191-7 is supplied in tube packaging. The M24308/23-11F is supplied in bulk packaging. Packaging selection depends on inventory management and assembly process requirements.

Q: Are there temperature range differences between the substitutes?

A: Yes. The 207830-4 and 5745191-7 both operate from -55°C ~ 105°C. The M24308/23-11F extends the upper limit to 125°C, providing a wider operating range suitable for higher-temperature environments.

Q: What contact finish thickness differences exist?

A: The 207830-4 specifies 30.0µin (0.76µm) gold contact finish thickness. The 5745191-7 specifies flash thickness (not quantified). The M24308/23-11F specifies 10.0µin (0.25µm). These variations may affect contact durability and mating cycle life in high-cycle applications.
