Substitute Part Grouping Explanation

Substitution of the 29F0818-1SR is determined by strict equivalence across the following critical parameters:

• Impedance @ Frequency: 119 Ohms @ 100 MHz (electrical performance requirement)
• Current Rating (Max): 6A (thermal and power handling capability)
• DC Resistance (DCR) (Max): 10mOhm (conduction loss specification)
• Number of Lines: 8 (functional configuration)
• Filter Type: Power Line (application category)
• Package / Case: 16-SMD, Flat Leads (physical and electrical interface)
• Mounting Type: Surface Mount (assembly compatibility)
• Operating Temperature: -40°C ~ 125°C (environmental operating range)
• Size / Dimension: 0.450" L x 0.177" W (11.43mm x 4.50mm) (PCB layout compatibility)

The substitute part 29F0818-1SR-10 maintains identical electrical specifications and functional parameters. The primary difference is the packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete), along with minor physical height variation and enhanced regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 29F0818-1SR-10 is the direct electrical and functional equivalent of the 29F0818-1SR. Selection of the substitute part is based on the following engineering factors:

Product Status: The 29F0818-1SR is classified as obsolete, while the 29F0818-1SR-10 maintains active product status with Laird-Signal Integrity Products. Active status ensures continued manufacturing support, availability, and supply chain reliability.

Regulatory Compliance: The 29F0818-1SR-10 is ROHS3 compliant, whereas the original part is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the substitute part satisfies these regulatory obligations.

Physical Compatibility: The substitute part exhibits a reduced maximum height of 0.165" (4.19mm) compared to 0.190" (4.83mm) for the original part. This dimensional reduction provides improved PCB layout flexibility and does not compromise electrical performance or thermal characteristics.

Packaging Format: The 29F0818-1SR-10 is supplied in Tape & Reel format, which is standard for automated assembly operations. The original part bulk packaging is less suitable for high-volume production environments.

All critical electrical parameters—impedance, current rating, DC resistance, number of lines, and operating temperature range—are identical between the two parts, confirming direct substitution capability.

Frequently Asked Questions (FAQ)

Q: Can the 29F0818-1SR-10 be used as a direct replacement for the 29F0818-1SR in existing designs?

A: Yes. The 29F0818-1SR-10 is electrically and functionally identical to the 29F0818-1SR across all critical parameters: 119 Ohms impedance at 100 MHz, 6A current rating, 10mOhm DC resistance, 8-line configuration, and identical operating temperature range. The substitute part is pin-compatible and footprint-compatible with the original design.

Q: What is the significance of the height difference between the two parts?

A: The 29F0818-1SR-10 has a maximum height of 0.165" (4.19mm) compared to 0.190" (4.83mm) for the 29F0818-1SR. This 0.025" (0.64mm) reduction does not affect electrical performance or thermal management. The lower profile may provide advantages in space-constrained PCB layouts.

Q: Does the RoHS3 compliance of the 29F0818-1SR-10 affect its electrical characteristics?

A: No. RoHS3 compliance is a material composition and manufacturing process specification that does not alter the electrical performance, impedance, current rating, or DC resistance of the component. All electrical parameters remain identical to the original part.

Q: Is the Tape & Reel packaging of the 29F0818-1SR-10 compatible with manual assembly?

A: Tape & Reel packaging is designed for automated pick-and-place assembly systems. For manual assembly operations, components must be removed from the tape. The electrical and mechanical properties of the component are unaffected by packaging format.

Q: Are there any thermal or frequency response differences between the two parts?

A: No. Both parts operate across the identical temperature range of -40°C to 125°C and maintain the same impedance specification of 119 Ohms at 100 MHz. Thermal and frequency response characteristics are equivalent.

Q: What is the reason for the obsolescence of the 29F0818-1SR?

A: The 29F0818-1SR is classified as obsolete by the manufacturer. The 29F0818-1SR-10 represents the current active product offering with identical electrical specifications, improved regulatory compliance, and modern packaging standards suitable for contemporary manufacturing processes.
